The sonographer may show the fetus, a small curly white object at this stage. The gestational sac enlarges by about 1.13 mm each day and ranges from 2-3 mm. However, the embryo will look like a coiled tube, and you will no longer see the ball shape.

Pubmed said:

When the fetal pole was in the longitudinal position, the distance between the fetal pole and the yolk sac was measured in millimeters (mm).
